Semi-Conductor Production
Ultra-High Purity Cleanroom Solutions for Semiconductor Production
Semiconductor fabrication is the pinnacle of controlled environment engineering. As transistors shrink to the nanometer scale, the tolerance for atmospheric contamination reaches near-zero levels. Rayshen provides the high-performance infrastructure required for modern Fabs, delivering specialized Semiconductor Cleanroom Equipment that meets ISO Class 1 to ISO Class 5 standards.
Our engineering focus for the semiconductor industry centers on three pillars: Ultra-low particulate air (ULPA) filtration, precise laminar airflow via Fan Filter Units (FFU), and advanced personnel decontamination.
High-Performance Air Management: The Engine of the Fab
In semiconductor production, air is treated as a critical utility. It must be move in a perfectly unidirectional (laminar) path to sweep particles away from silicon wafers instantly.
Fan Filter Units (FFU) for Semiconductor Fabs
The Fan Filter Unit (FFU) is our most sought-after product for semiconductor facilities. Our units are engineered to handle the 100% ceiling coverage required in Grade A zones.
- EC (Electronically Commutated) Motors: These motors offer superior energy efficiency and allow for digital speed control to maintain exact pressure differentials.
- Ultra-Low Vibration: We use precision-balanced impellers to ensure that the FFU does not transmit mechanical vibrations to sensitive lithography or etching equipment.
Advanced FFU Control Systems
- Group Control Logic: Hundreds of FFUs can be managed via a single central gateway, allowing for real-time adjustments to air velocity across different Fab sectors.
- Filter Pressure Monitoring: Integrated sensors alert facility managers when filters begin to load, preventing unplanned downtime.
ULPA and HEPA Filtration: Reaching 99.9995% Efficiency
While pharma uses HEPA, the semiconductor industry often demands ULPA (Ultra-Low Particulate Air) filtration to capture particles that are invisible to the human eye but deadly to microchips.
U15 & U16 ULPA Filters
Our High-Efficiency Filters are manufactured in a controlled environment to ensure zero outgassing and maximum purity.
- Efficiency: Certified 99.9995% at 0.12 microns.
- Mini-Pleat Media: Utilizes ultra-fine glass fiber to provide the highest possible surface area with the lowest resistance.
Specialized Frame and Seal Options
Gel Seal (Fluid Seal): The industry standard for semiconductor Fabs, providing a 100% airtight, knife-edge seal that eliminates bypass air.
PTFE Media Options: For environments where boron or other chemical outgassing from traditional glass fiber is a concern.
Personnel Decontamination: Industrial Air Showers
Humans are the primary source of organic contaminants and skin dander in a Fab. Rayshen’s Industrial Air Shower is the essential barrier between the gowning room and the production floor.
High-Velocity Air Shower Systems
- Particle Scrubbing: High-velocity nozzles (25 m/s) deliver concentrated HEPA-filtered air to dislodge sub-micron dust from cleanroom suits.
- ESD-Safe Interiors: Featuring grounded stainless steel panels and optional ionizing bars to neutralize static charges that attract dust to personnel.
Logic-Controlled Interlocking
- Programmable Cycle Times: Adjustable from 0-99 seconds to meet specific facility protocol requirements.
- Emergency Override: Integrated with fire safety systems for instant door release during facility emergencies.
Material Handling and Transfer Solutions
Silicon wafers are highly sensitive during transport between the Front Opening Unified Pod (FOUP) and processing tools.
Dynamic Pass Boxes with Ionization
To maintain a Class 1 environment during transfer, our Dynamic Pass Boxes are equipped with:
- Dedicated FFU/Filter: Independent air recirculation to ensure the transfer chamber remains cleaner than the surrounding lab.
- Anti-Static Features: Ionizing blowers to remove electrostatic charges from wafer carriers.
SS Workstations & Desiccator Cabinets
We manufacture SS 304/316L Workbenches designed with perforated tops to allow laminar airflow to pass through, preventing particle accumulation on work surfaces.
Why Rayshen for Semiconductor Cleanrooms?
As a specialized Cleanroom Equipment Manufacturer, we understand that semiconductor Fabs operate 24/7/365. Reliability is our core value.
ISO 14644 Validation and Compliance
- Particle Count Verification: We provide on-site validation using laser particle counters to verify ISO Class 1-5 compliance.
- Filter Integrity Testing (PAO/DOP): Ensuring that every ULPA and HEPA filter is installed with a perfect, leak-free seal.
